Classification of Xenon
Xenon (Xe) is classified as a non-metal. It belongs to Group 18 of the periodic table, known as the noble gases. These elements are characterized by their full valence electron shells, which contribute to their general inertness and non-metallic nature.
Observable Physical Properties
Color and Texture
At standard room temperature and pressure, Xenon is a colorless gas. It is also odorless and tasteless. Due to its gaseous state, the concept of texture, as one would apply to a solid or liquid, is not directly applicable.
State of Matter
Xenon exists as a gas at room temperature (approximately 25 °C) and standard atmospheric pressure. This is a defining characteristic of noble gases under these conditions.
Phase Transition Temperatures
Xenon undergoes phase transitions at very low temperatures.
- The melting point of Xenon is approximately -111.7 °C. Below this temperature, it transitions from a liquid to a solid state, forming a crystalline structure.
- The boiling point of Xenon is approximately -108.1 °C. This is the temperature at which it transitions from a liquid to a gaseous state at standard atmospheric pressure. Its presence in trace amounts in the atmosphere, alongside other noble gases, indicates its gaseous state under typical ambient conditions found across India and globally.
